Thank you for visiting the Windows Internet Explorer Testing Center!

In conjunction with the Beta 1 release of Internet Explorer 8, we’re posting a set of tests we are using to validate our interpretation and implementation of the CSS 2.1 specification. We’re doing this so we can get some feedback from you, the web designers and developers, on the tests we’ve submitted to the W3C for inclusion into the W3C’s CSS Working Group Test Suite.

We know how challenging it can be to build one site that works in every browser and we know it’s just getting harder as the technology advances and customer expectations rise. The Internet Explorer team is serious about making it easier for you to build the web in a standardized way. Because there are ambiguities and options in any specification, we’ve created these tests to verify our current implementation of the CSS 2.1 specification in IE8 Beta 1. These tests will eventually cover the breadth of the properties for CSS 2.1 that are implemented in future IE8 milestones. We welcome and desire your feedback on the tests prior to these becoming official tests in the CSS suite. Please post any corrections or additions you may have to the tests in the W3C CSS2.1 Test Suite mailing list.

Thank you,
